openclaw-k8s-toggle-operator 0.0.3

Matrix-controlled Kubernetes deployment toggle operator

openclaw-k8s-toggle-operator

Matrix-controlled Kubernetes deployment toggle operator. Connects to a Matrix homeserver with E2E encryption and listens for chat commands to scale a K8s deployment between 0 and 1 replicas.

Extracted from the inline clawdbot_operator.py ConfigMap in the Ansible infrastructure repo (roles/kubectlstuff/files/clawdbot_operator.py).

Status

Beta (v0.0.1) — the core Matrix bot and K8s scaling loop is implemented. The project scaffolding (packaging, Docker image, CI) is in place.

Bot Commands

Send these as plain text messages in a Matrix room with the bot (encrypted or unencrypted):

Command	Action
start / on	Scale deployment to 1 replica
stop / off	Scale deployment to 0 replicas
status	Show deployment replica counts
help	Show available commands

Only users listed in ALLOWED_USERS can send commands. The bot auto-accepts room invitations from allowed users.

Architecture

• Runs as a single-replica Deployment in a dedicated namespace
• Uses the Kubernetes Python client with in-cluster config to patch deployment scale
• Connects to Matrix via matrix-nio with E2E encryption (libolm)
• TOFU device trust — automatically trusts all devices of allowed users
• Crypto store must be on a persistent volume or the bot loses decryption keys on restart
• Auto-reconnect loop with exponential backoff (max 20 retries)
